Color-changing device of computer embroidery machine

Abstract

The invention provides a color-changing device of a computer embroidery machine, aiming at solving the problems of bad quality of embroidery products caused by low marginal definition of embroidery patterns and not clear color differences of patterns when the needle position signals collected by a color-changing device generate return differences, and the device accidents happening caused by false needle position signals transmitted by a needle position signal collecting device in the prior art. The color-changing device of the computer embroidery machine comprises a needle rod frame driving device and a needle position signal collecting device; the needle rod frame driving device comprises a driving seat for driving the needle rod frame, a driving seat driving device for driving the driving seat to carry out linear reciprocal displacement and a driving seat guide rail; the needle position signal collecting device comprises a potentiometer and a potentiometer shaft driving device; the potentiometer and the driving seat perform synchronous linear reciprocal displacement; and the potentiometer shaft driving device can transform the linear displacement movement of the potentiometer into gyration movement of a potentiometer shaft. With the adoption of the structure of the color-changing device of the computer embroidery machine, not only can accurate needle position signals be provided, but aslo safe and reliable color changing processes can be guaranteed.

Description

technical field [0001] The invention relates to a computerized embroidery machine, in particular to a color changing device for a computerized embroidery machine. Background technique [0002] With the improvement of people's quality of life, strict requirements have been placed on the quality of daily necessities such as clothing, home and office, especially embroidery products, exquisite and colorful embroidery patterns, clear pattern edges, and uniform pattern luster are becoming more and more popular. favored by people. [0003] The computerized embroidery machine color changing device is a necessary mechanism serving the embroidery machine. Its function is mainly to make the color of the embroidery pattern no longer a single color. [0004] The color changing device of the computerized embroidery machine mainly includes two parts, one part is the needle bar frame driving device, and the other part is the needle position signal collecting device. A lot of needles are a...

AI Technical Summary

Problems solved by technology

[0008] The purpose of the present invention is to aim at the hysteresis generated by the needle position signal collected by the color changing device in the prior art, so that the edge definition of the embroidery pattern is low, the color layers are not clear, the quality of the embroidery is low, and the needle position signal acquisition The device sends a false needle position signal, which leads to defects and deficiencies in equipment accidents, and provides a safe and reliable color changing device that can provide accurate needle position signals
